My way of thinking is that, if the following things are true:
1. You only invest what you can afford to lose,
2. Your quality of life is already at a decent level,
3. You understand Bitcoin tech,
4. You are not greedy,
...then you don't panic easily. You can HoDL down to even under $1k and not flinch. "Let it go to zero. I'm already doing OK, I don't really need it." That's what I say to myself when there's a big dip, and that's because of (1), (2), and (4). And if there's a big dip, I try to buy more coins, because of (3), but always respecting (1).
If you get scared easily and chicken out at big dips, you're doing it wrong.
Yep, this is true above "He has admitted before that he panicked like a little girl."
"Brad, not trying to rub things in. But I'm curious how a savvy BTC guy like you who has been into BTC as long as you have sold near the exact bottom of the market?"
Yep on the above....all them pesky 'real-life circumstances' below
Well, since HODL mode, except for mining and electricity and equipment, etc....I managed to HODL through it all from 2013 until 12/24/18 I dumped the 13 BTC.
But at that time (see previous posts) I had retired at 62 years at the ATH and was living off income from crypto until 66 years and 2 months and then I would
crypt
tap into my previous traditional investments at that point. Thus 30 years working with dev disabled/house paid no debt lifestyle...switches to crypto carry over
which I thought I had 3 years of altcoins to cover such ..burnt through that in 9 months with the dump/crash...again same lifestyle then without crypto and
66 years 2 months soc sec and traditional 'balanced' investments at my 65 years of age...again the same lifestyle. So again, retired with no change in money
or lifestyle or what I thought. So dumped the 13 BTC to get through next year or so with altcoins till 66 years and 2 months plan. ie thus panic and sold 13 BTC.
(hey, I only ran in the battle that one time..jeez). So my one great dump of any kind from HODL mode since 2013 and 13 BTC and dumping at the low was based
on panic and circumstances...I really, really was not gonna go back to work for another 1.5 to 2 years so yeah...I dumped 13 BTC indeed and assorted altcoins (at
least they were at the high compared to now)
Then as previous posts state had change in circumstances and monthly income improvement middle of 2019 ...thus the 13 BTC panic sale though understandable
was an overreaction..or not ..without the change in circumstances monthly improvement addition the 13 BTC had to go..since that no longer applies and such
I managed to worm back 4.5 BTC of the original 13 BTC sold in 2019 till now. So any way you are correct the panic did not come out of the blue, real-life pressures
did indeed cause me to panic sell, but one does not at the beginning of 2018 at ATH expect an 85% dump in BTC price and 95% dump in altcoins or whatever the %
ugly that it was. Anyway, circumstances have changed, discretionary money into my traditional investments does not seem prudent at this time, I expect a recession
thus HODL of crypto is probably a better bet now than it was even at these prices in 2018 given the current real-life and world financial health circumstances IMHO.

but what do I now... I panic sold 13 BTC at $3,965 USD...much angst...alas, lost the faith...a lapse in kool-aide drinking refreshment.

My post above was general. I wasn't aware that you had 100 BTC at the time, and also your age. Spending 13 out of 100 BTC is not a big deal. Like JJG says, I wouldn't worry about getting back to some nice round number. By this mentality, you would not want to spend anything in the future, so as not to spoil its roundness? Doesn't make sense to me, although I'm also kind of OCD about round, symmetrical things, powers of two, and other weird things.
You are fine, and pretty soon you'll be "fuck you" rich. I wouldn't worry
